IMPROVEMENT IN OO0KING-STOVES.

TO ALL WHOM IT MAY O ONOERN:

Be itknown that I, Enasrus D. Wasrolv, of Taunton,'in the county of Bristol, and State of h lassaohusetts, have invented certain new and useful Improvements in cook'ing stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference-beinghad to the accompanying drawings, making a part of this specification, in which- Fi ure 1 is a sectional View through the centre, and

Figure 2 a birds-eye View of a portion of the top ofthe stove, with the upper plate removed, showing the various fiu es.

The same letters refer to the same'parts in both figures. v

A represents the fire-chamber; B B, the front and back linings; O, the grate; D, the ash-pit; E, the oven; F, the return-flue; G,.the hollow top; H, openings for the admission of cold air; I, an opening connecting the lower partof the oven with the flue M; J,'small holes for'the-passage of the heated air of the oven into the direct draught K.

The operation is asi'oliews: The cold air entering the hollow or double top G at H, at the under side of that portion of the top that projects beyond or outside of the front jamhs of the stove, follows the course indi cated by the arrows, (that is, from the front to the back of the stove,) passing directly over the fire, and-down the flue M, it becomes heated in its course, and enters the even through the opening I. Here it imparts its heat to whatever may be in the oven, and circulatingtherein, it passes oil through the holes J in the front ovenplate into the direct draught K, from whence-it is carried into the pipe.

By having the whole top composed of two plates of metal, with a current of air between them, there is not that liability to warp or settle that is such a prolific source of complaint in all single-topped cooking-stoves; and also, the air being heated as it entersthe oven, reduces the amountof fuel required to obtain the degree of heat in the oven necessary to success in baking, and this heated air, thus introduced, equalizes the heat in the whole oven, baking as well on the rack, midway, as on the bottom plate.

I am-awaro that it is not new to introduce heated air into the oven of a stove by fiucs arranged between the oven and the fireplace, and extending over the top of theoven, and between it and the smoke-escape flue of the fireplace, such being asrepresented in the United States Patent, No. 35,141.

My invention differs materially from such, as my horizontal hot-air flue is not interposed between the ovens and the smoke-escape flue leading from the fireplace, but is arranged over such flue, so as to cause the oven to be heated not only by heat abstracted from such smoke-flue and radiated through the top of the oven, but by air passing over the top of the smoke-flue. Thus it will be seen that with my improvement I get heat into the oven from both the top and bottoru of the smoke-flue, which is not the case in the stove described in'such patent. I am aware that it is notjnew to arrange an air-heating flue ever the top of the smoke-flue of astove, and

to open such air-heating flue into arflue surrounding an oven raisedabove the smoke-flue, the even being heated by the air--he'ating'flues only, such being as shown in the United States Patent, No. 21,731. My invention differs from this latter, as I introduce the hot air into the' ovcn and heat the oven by smoke-fines going around it.

What, therefore, I claim as my invention or improvement, is as follows:

I claim the arrangement of the air-heating llue G,'tlie fireplace A, the smoke-flue K, the oven E, and the air-flue or fines M, provided with one or more openings, I, to lead air into the even, as set forth.

I also claim the arrangement of one or more openings, J, with the flue G, the fireplace A, the oven E, one or more openings I, the ilue or flues M, and the air-flue I I also claim the arrangement of the air-flue G, and its induction-openings H, so as to extend over and in front of the front plate of the fireplace, as represented.

I'also claim the arrangement of the air-fiucs G M, the oven E, the fireplace A, the smoke-fine K, and flues F, underneath and in rear of the oven, the even being provided with the air-induction and educt-ion openings I J, as set forth.
